Manganese Catalysts Offer a Lasting path to Hydrogen Fuel Storage
New research demonstrates the potential of manganese-based catalysts to efficiently convert carbon dioxide into formate, a promising hydrogen storage material, offering a cost-effective and environmentally friendly alternative to traditional methods.
New Haven, CT & Columbia, MO – February 5, 2026 – In a notable advancement towards sustainable energy solutions, scientists at yale University and the University of Missouri have unveiled a novel approach to carbon dioxide conversion utilizing manganese-based catalysts. Published in the prestigious journal Chem, the study details how these readily available and inexpensive catalysts can efficiently transform carbon dioxide into formate, a compound increasingly recognized as a viable medium for hydrogen storage. This breakthrough addresses a critical challenge in the widespread adoption of hydrogen fuel cell technology – the efficient and affordable storage of hydrogen.
The Promise of hydrogen Fuel Cells
Hydrogen fuel cells represent a clean energy pathway, generating electricity through a chemical reaction between hydrogen and oxygen, with water as the only byproduct. However, the practical implementation of this technology has been hampered by the complexities and costs associated with hydrogen production, transportation, and, crucially, storage. Current hydrogen storage methods ofen involve high-pressure tanks or cryogenic cooling, both of which are energy-intensive and pose safety concerns.
“Carbon dioxide utilization is a priority right now, as we look for renewable chemical feedstocks to replace feedstocks derived from fossil fuel,” explains Yale Professor Nilay Hazari, senior author of the study and chair of the Chemistry department at Yale’s Faculty of Arts and Sciences.
Formate: A Practical Hydrogen Carrier
formic acid (HCOOH), the protonated form of formate, is already produced on an industrial scale and finds applications in diverse industries, including preservation, antibacterial treatments, and leather processing.It’s potential as a hydrogen carrier stems from its ability to release hydrogen upon demand, making it a safer and more manageable alternative to storing hydrogen gas directly. Though, current formate production largely relies on fossil fuels, diminishing its environmental benefits.
The Yale-Missouri team’s research focuses on developing a sustainable method for formate production – directly from carbon dioxide captured from the atmosphere. This dual benefit – reducing greenhouse gas concentrations and creating a valuable chemical product – positions formate as a key component in a circular carbon economy.
Overcoming the Catalyst Challenge
The conversion of carbon dioxide into formate requires a catalyst to facilitate the chemical reaction. Traditionally, effective catalysts have relied on precious metals like platinum, palladium, and ruthenium. These materials, however, are expensive, scarce, and often exhibit toxicity, hindering their widespread application. More abundant metals, while cost-effective, typically lack the stability and efficiency required for sustained catalytic activity.
The research team tackled this challenge by focusing on manganese, a considerably more abundant and less expensive metal. Through innovative catalyst redesign, they successfully extended the operational lifespan of manganese-based catalysts, achieving performance levels comparable to, and in certain specific cases exceeding, those of precious metal alternatives.
“The key betterment came from adding an extra donor atom to the ligand design,” explains Justin Wedal, a postdoctoral researcher at Yale and lead author of the study. “This modification stabilized the catalyst, preventing its degradation and maintaining its effectiveness over extended periods.” Ligands, in this context, are molecules that bind to the metal atom and influence its reactivity.
Implications for a Cleaner Future
This breakthrough extends beyond carbon dioxide conversion. The researchers believe the principles behind their catalyst design can be applied to other chemical reactions,perhaps revolutionizing a broader range of industrial processes.
“I’m excited to see the ligand design pay off in such a meaningful way,” Wedal added.
the study was a collaborative effort, with contributions from Yale researchers Brandon Mercado and Nicole Piekut, and was funded by the U.S. Department of Energy’s Office of Science. This research represents a significant step forward in the development of sustainable chemical processes and offers a promising pathway towards a cleaner, more energy-efficient future.
